The SLI information guide

Recommended Posts

Posted · Original PosterOP

Heyyo,

Good guide. The only recommendation I'd add? A link to this table of user-found SLI bits. It's quite the comprehensive list of SLI bits for either better SLI scaling or support for SLI in games that don't have it.

http://www.forum-3dcenter.org/vbulletin/showthread.php?t=509912

and of course in order to use those bits the program NVIDIA Inspector is needed.

Sure, I'll add it in. I'm always glad to expand the guide some.

So say I want to dual SLI. I currently have a gtx 780 from evga superclocked. Is it possible for me to dual sli with cards from the new 900 series? I just want to know if it's possible to dual sli with anything better than a gtx 780 in the nvidia lineup

What can I SLI?

 
You:
CAN use mismatched cards if you are driving a second or third monitor from the extra card. I believe this does not even need a SLI bridge.
CAN use mismatched cards if you are driving PhysX on the second card.
CAN use the same cards in non-performance-boosting mode (driving extra monitors) to do triple monitor gaming.
CAN use cards with different core clock speeds in SLI without one card being slowed to match the other.
CAN use cards with different memory clock speeds in SLI without one card being slowed to match the other.
CAN use cards from different manufacturers as long as their specs are the same (I.E. "MSI GTX 780 lightning" + "Gigabyte GTX 780 Windforce" will work).
CAN use cards with different forms of cooling in SLI (reference cooler + non-reference cooler).
 
MAYBE can use mismatched cards driving extra monitors for triple monitor gaming (I do not know, so I am leaving it as a maybe. ANYBODY who can test and let me know, please do.)
MAYBE can use mismatched cards to force higher levels of CSAA (like 64x CSAA) on games. As above, I cannot test it.
 
CANNOT use mismatched cards in performance boosting mode.
CANNOT use cards with different cores even if the same name (GK104 GTX 660 (OEM) + GK106 GTX 660 will fail).
CANNOT use cards with different vRAM sizes even if the name and core is the same (GTX 770 4GB + GTX 770 2GB will fail).
CANNOT use cards with different memory bus width even if the same name and core is the same (GTX 760 192-bit (OEM) + GTX 760 256-bit will fail)

The only way you'd be able to use the 780 is as a PhysX card or to run extra monitors.

I've updated quite a bit of this guide with information I've verified lately. It's enough information that I think it's worth a bump.

Oh yeah, that link you provided of the notebookreview forum, it was very, very helpful. I really didn't notice that thing at all, even though I read Maxwell's review on Tom's Hardware. That's another thanks for you. Nice going!!!! ;)

Not a problem, that's what these guides are for. When DX12 is out and running full steam I bet I'm going to need to make a lot of changes to this >_<. Aaaand now to handle HBM on the vRAM guide.

I have a couple questions if anyone cares to help me out??
I just ordered a second 970, and this will be my first SLI rig.
How well does gsync work with SLI??
My gsync monitor has killed all the lag and screen tearing I had, and I was hoping that it might help with micro stutters associated with SLI.
I haven't been able to find any current info on it??
I saw people say its awful a year ago, then others say its fixed?
I also got myself a new board, because my old one wasn't "SLI Ready"
It had 16x and 8x, would I have been fine using 16 and 8?? lol
Not sure if i want to know lol

From what I know, it should work fine right now.

SLI has no microstutters unless your FPS is very low, so I don't know what microstutters you're attempting to kill... unless you plan to run your game at 35fps?

Cannot comment on that.

Since a consumer intel board only has 16 PCI/e lanes, then you'd never have gotten 16x + 8x. You'd get 8x and 8x, and that's fine for SLI. If you're on an AMD board, then you should have more than enough lanes, though I'd quicker tell you to buy a new intel board.

 

I would suggest you buy a single 980Ti instead of two 970s, as per my recommendation section of this guide. SLI is not being supported as well as it was a couple years ago by devs' interests and by nVidia's tech.

I already had a 970, so it was a little cheaper to grab a second 970.
I don't plan on runninng fps anywhere near that low, so that's awesome to hear.
If you don't mind me asking yet another question, what is the point in the more expensive SLI board versus the non SLI then??
I went from http://www.newegg.com/Product/Product.aspx?Item=N82E16813128713 to http://www.newegg.com/Product/Product.aspx?Item=N82E16813130771
Thanks for your help, I really appreciate it

Well you would get more raw power that way anyway in games that support it... still a single 980Ti would do you better though.

Some non-SLI boards don't have a second PCI/e x16 slot, and some even if they have it, aren't configured to run it at 8x to allow for 8x/8x configs necessary for SLI. AMD can use 4x for Crossfire, so a board can be "crossfire capable" without being "SLI capable".

From what I see, there's absolutely no reason for you to have changed motherboards. Going by the spec sheet provided on Newegg, that is. Of course, know that boards have different VRM types etc that might affect CPU overclocking and the like, but I'm not very well versed in those particulars.

Well crap.
I stumbled onto Linus's video about pcie lanes after I ordered it, and started to second guess my decision.
Atleast this one matches my 970's colors I guess lol
Thanks for clearing that up for me.
Have a great day!

Heyyo,

One exception to the SLI VRAM rule? It can "work" with different VRAM amounts but there is the risk of crashing.

DifferentSLIAuto has worked for some users, heck, even for some they could get SLI on non-SLI certified boards... but of course, it's at that users discretion.

I mainly recommend DifferentSLIAuto to users who have two GTX 970s but it won't allow them to enable SLI.

https://github.com/EmberVulpix/DifferentSLIAuto/releases

At least one user on these forums have gotten it to work with different VRAM GPUS.

Mmm... I'll consider that. I might warn against betting on it and linking to it, but allude to its existence, similar to how I did it with the SLI on/off situation for laptops (which I do use).

And how long did it take you to make this? Excellent job, I know a lot more then I did. 


Is Firewatch playable on ultra at 11 fps? Yes it is!

Check meh profile for my laptop specs, don't want to scare anyone without warning them

Need a part list or an opinion? PM me and I'll get back to you!

80% of the information in the guide was created just from me using SLI on my notebook with various games and talking to a couple other SLI notebook owners over the course of about 8 months.

 

The remaining 20% was discovered after; 10% being data collected from other users (as I don't have maxwell video cards, or SLI on desktops) and 10% just people correcting my information on other forums.

LOL it adds up to 120%, the amount of Hz in your monitor.

Did you talk about micro stuttering anywhere. I read everything that could have contained that section. Maybe I am to tired but then I'd like you to show me where it is.

I had been tinkering with getting an SLI confit but I am sooooo solo afraid of the stutter since I am very sensitive to fps drops, dips, varying frame times, etc.

Edit: you are officially allowed to put the tl;dr stamp on my face. I just read the 2. Page.

So micro stutter is not really a thing anymore? Wow... That is ... AMAZING!!

Actually, it usually happens around 30-35fps. It's especially bad in GTA V's main menu before you load story or online mode because it's locked to 30fps xD.

 

Once you're at say... 40fps or above, you'll experience no microstuttering unless the game needs a lot of optimization.

 

I had considered adding it into the guide before... but most users don't play at 35fps in SLI. I think I'll add it in the top part, where I clear misconceptions. Thanks for reminding me!

I was planning to go SLI 980's when I get my 1440p Monitor but reading this information, I am kinda worried to do so. First world problems lol

980Ti first. I can't stress that enough right now. Next thing you know you buy three unreal engine 4 games (like Ark Survival Evolved being one) and all of a sudden you're on a single 980 again.

 

I don't know why engines like UE4 are bringing out such intense visual effects and then killing SLI support, but it is what it is. Even Kojima's Fox Engine, as nice as it is, doesn't love SLI all that much. Nobody ever said anything about it, but MGSV: GZ seems to cap out near ~75% util on each GPU. Or games take many months before they work really well with SLI now.

 

I don't think two 980s is particularly a bad option, but considering the boost that a single 980Ti grants and the little price difference, it's a no brainer. If the 980s were $400, it would be different. The R9 390X cards are ~$420, yes, but lack of windowed mode support in Crossfire and lack of overclockability on the AMD cards prove it less desirable to be a card to run in multi-GPU states.

 

So I just tell people to get a 980Ti first before even considering multi-GPU. I would recommend the Fury X as a 980Ti alternative, but it seems to have some low util problems, and regardless of what anybody says, that 4GB can be an annoyance with the amount of power that the cards can crank out (high resolutions + high levels of multisample-type AA are a desirable thing, regardless of what anybody else says, far less those who use multiple monitors and have Windows use up some of their vRAM too).
